v1.3.0

This release adds two things:

1. It utilizes dnsLookup passed through options, and got-ssrf now utilizes cached DNS lookups if provided.
2. It adds memoization to hopefully help speed up the (potentially) computationally expensive operations, such as canonicization (which involves parsing whole ass HTML document) and tracker stripping (which involves matching tons of regex)

• fix bugs f34cc42
• add memoization to tracker stripping and canonicization e862d4b
• utilize dnsLookup 7e7606f
• add default dns cache 094cb75
